As we're about to trap CP15 accesses and handle them at EL2, we
need to evaluate whether or not the condition flags are valid,
as an implementation is allowed to trap despite the condition
not being met.
Tagging the function as __hyp_text allows this. We still rely on
the cc_map array to be mapped at EL2 by virtue of being "const",
and the linker to only emit relative references.

As we plan to do some emulation at HYP, let's make kvm_skip_instr32
as part of the hyp_text section. This doesn't preclude the kernel
from using it.

Add the bit of glue and const-ification that is required to use
the code inherited from the arm64 port, and move over to it.

It would make some sense to share the conditional execution code
between 32 and 64bit. In order to achieve this, let's move that
code to virt/kvm/arm/aarch32.c. While we're at it, drop a
superfluous BUG_ON() that wasn't that useful.
Following patches will migrate the 32bit port to that code base.
